Planet eater
From Tardis Wiki, the free Doctor Who reference
Planet eaters were enormous spacecraft constructed to demolish asteroids and planetoids in order to clear space lanes. The debris would be burned in giant furnaces to provide the ships with fuel. They were decommissioned and mostly scrapped, although some came to be owned by museums and collectors. Vilgreth stole a planet eater from Professor Patrick Trethui's collection and began wandering the galaxy, regarding the ship as his home. Before Vilgreth could destroy the planet Ormelia, he and his ship were destroyed by a bomb planted by Ormelian agent Stelpor. (AUDIO: Last of the Titans)
